ServiceTrade empowers commercial service contractors in fire protection, HVAC, mechanical, electrical, and beyond to service smarter and scale faster. Our platform helps thousands of contractors maximize technician productivity, deliver digital-first customer experiences, and grow profitably. When skilled techs are hard to find and manual systems slow you down, ServiceTrade is how the best contractors pull ahead.
Under the hood, that mission runs on a serious piece of engineering: a multi-tenant SaaS platform built on PHP, Doctrine, MySQL, MongoDB, and AWS, processing the real-time workflows that keep commercial service operations moving. It's battle-tested, revenue-generating, and architecturally complex. We're hiring a Staff Engineer to help write that chapter.
You'll join a team that's investing in the long-term health of this platform: evolving the architecture, modernizing incrementally, improving reliability, leaning into AI acceleration tooling, and building the infrastructure to scale the next phase of growth, all without breaking what works for the thousands of contractors who depend on us every day. This is a hands-on technical leadership role. You'll own critical architectural decisions across backend and infrastructure, mentor engineers, and shape how we build software in this new world of agentic AI.
If you've ever looked at a complex production system and thought "I know how to make this better, one piece at a time," this is the job.
